El oxalic acid en rhubarb leaves binds con calcium en el blood a form insoluble calcium oxalate crystals. Estos crystals physically damage el kidney tubules como ellos precipitate, causing acute kidney injury. Additionally, el sudden drop en blood calcium (hypocalcemia) puede cause muscle tremors, tetany, y cardiac arrhythmias.

El rhubarb stalks — el pieza humans eat — contain mucho inferior oxalate concentrations y son generally seguro para la mayoría dogs en pequeño amounts. El stalks contain mostly fiber y agua con trace oxalates (~0.1-0.3% oxalic acid por weight). UN dog would necesitar a eat several pounds de rhubarb stalks a reach toxic oxalate levels. But si usted grow rhubarb y su dog tiene access a el garden, el leaves son el concern — they're large, attractive, y puede cause significant toxicity. Si su dog ate rhubarb leaves: emergency vet.

Síntoma Timeline — Qué a Expect & Cuando a Act

Time desde ingestion es el la mayoría crítico factor en toxicity outcomes. Esto es un general timeline — individual responses vary based en weight, breed, age, y pre-existing conditions.

Time Desde Ingestion	What's Happening	Síntomas	Su Action
Primero 30 Minutes	Toxin enters el stomach. Absorption begins. Para la mayoría toxins, esto es el golden window para intervention.	Puede ser none visible yet. Mild drooling, lip-smacking, o restlessness posible.	Llamar vet o ASPCA Poison Control (888-426-4435) immediately. Hacer NO wait para symptoms.
30 Min – 2 Hours	Toxin enters el pequeño intestine. Systemic absorption accelerates. Para la mayoría toxins, clinical signs comenzar en esto window.	Vomiting, diarrhea, lethargy, drooling, abdominal pain, restlessness o depression.	Transport a vet. Traer el substance packaging. Nota el time y estimated amount consumed.
2–6 Hours	Peak blood concentration para la mayoría toxins. Organ damage begins si el toxin targets liver o kidneys. GI symptoms intensify.	Persistent vomiting, bloody diarrhea, tremors, ataxia (wobbling), increased heart rate, fever o hypothermia.	Si no ya en vet: IR AHORA. Hacer no wait para "one más hour." Organ damage puede ya ser occurring.
6–24 Hours	Toxin es either siendo metabolized y excreted, o organ damage es progressing. Recovery o deterioration becomes clear en esto window.	Depends en el toxin: jaundice (liver), reduced urination (kidney), seizures, collapse, o gradual improvement.	Si hospitalized: follow veterinary guidance. Si recovering en home: monitorear closely para 48 hours. Any regression = return a vet immediately.
24+ Hours	Acute phase passing. Largo-term organ function y recovery trajectory son siendo determined. La mayoría pets eso survive past 48 hours recover fully.	Residual GI upset, fatigue, increased thirst/urination posible como el body clears metabolites.	Follow-arriba vet visit. Blood trabajar a verificar liver y kidney values. Bland diet para 3-5 days.
